8.3.1 Input Voltage Range (VIN1, VIN2)

With a steady-state input voltage range from 3 V to 36 V, the TPSM63604 module is intended for step-down conversions from typical 12-V, 24-V, and 28-V input supply rails. The schematic circuit in Figure 8-1 shows all the necessary components to implement a TPSM63604-based buck regulator using a single input supply.

Figure 8-1 TPSM63604 Schematic Diagram with Input Voltage Operating Range of 3 V to 36 V

The minimum input voltage required for start-up is 3.95 V. Take extra care to make sure that the voltage at the VIN pins of the module (VIN1 and VIN2) does not exceed the absolute maximum voltage rating of 42 V during line or load transient events. Voltage ringing at the VIN pins that exceeds the absolute maximum ratings can damage the IC.
